全球河流流量模拟，占452个单独经营的水库，通过定位他们的数字全球河流网络地图的TRIP，全球河流路由模型。使用新开发的算法确定每个水库的运行规则，该算法使用当前可用的全球数据，如水库蓄水量、预期用途、模拟流入量和下游需水量。该算法减少了水库释放和河流流量模拟的均方根误差，从早期的全球河流流量模拟，忽略水库运行或取代自然采取流出的算法。2年全球模拟结果表明，水库运行大大改变了个别流域的月流量（即，超过20%）。平均在大陆尺度上，最大的变化，每月河流流量从0%到34%不等，水库蓄水量的变化是小的总存储容量的比例。(c)2005 Elsevier B.V.保留所有权利。
A global river discharge simulation was conducted that accounted for 452 individually operated reservoirs by Locating them on the digital global river network map of TRIP, a global river routing model. An operating rule was determined for each reservoir using a newly-developed algorithm that used currently available global data such as reservoir storage capacity, intended purposes, simulated inflow, and water demand in the lower reaches. This algorithm reduced the root mean square error of reservoir release and river discharge simulations from that of earlier global river discharge simulations that neglected reservoir operations or substituted an algorithm for natural-take outflow. The 2-year global simulation results indicate that reservoir operations substantially altered monthly discharge for individual basins (i.e., by more than 20%). Averaged over the continental scale, the maximum change in monthly river discharge varied from 0% to 34% and the changes in reservoir storage were small as a proportion of the total storage capacity.
